Cultivation methods and precautions of Cymbidium grandiflora

Soil: It is best to use loose, breathable, well-drained humus soil for cultivating Cymbidium grandiflora Temperature: Maintain the maintenance temperature of Cymbidium grandiflora between 10-25 degrees.

Watering: Water the slightly acidic water quality for the large-flowered orchid, and the water temperature and room temperature should be consistent in winter.

Precautions: Apply a well-rotted cake fertilizer to the large-flowered orchid once a week. In the vigorous growth season, it is best to pour diluted liquid fertilizer every two weeks, or give a little compound fertilizer, etc.

The vitality of the large-flowered orchid is very vigorous, and it can live with water and soil, so it is super cost-effective to start in summer, which can be called a "super value explosion"! In addition, the large-flowered orchid tends to grow many flower stalks in winter and spring.

Cymbidium grandiflora prefers to grow in loose, airy and well-drained soil, so it is recommended to use humus soil. In addition, a mixture of moss, fern roots, charcoal, bark blocks, broken bricks, etc., is also a very good choice.

Try not to use ordinary culture soil and culture soil of cultivated national orchid, if the drainage and exhaust effect of the soil is poor, it is easy to lead to rotten roots of C. grandiflora.

Adequate watering should be given during the growing season, increased watering in the hot summer and less frequent watering in the cold winter, and the temperature of the water (as much as possible consistent with room temperature) should be paid attention to avoid frostbite to plant roots.

The pH value of the water used for watering the orchid is best.

In summer, when the light is strong, it needs to be shaded (large-flowered orchids do not like to be exposed to direct sunlight, so scattered light should be used), and it is best to shade about 50%. In autumn, in order to allow the plant to form flower buds and overwinter healthily, it can be exposed to more sunlight. In winter, it needs to be placed in a greenhouse with strong sunlight and high temperatures.

It is best to use a fertilizer with a ratio of 1:1:1 of nitrogen, phosphorus and potassium during the growth period, and the application rate of phosphorus and potassium can be increased during the flowering period.

Before use, it is necessary to dilute the fertilizer solution and adjust its pH to between, 1 to 2 days in summer (water and fertilizer are applied alternately), and in other seasons it is usually applied once every 3 days, and the fertilizer is stopped in winter.

Large-flowered orchid in the breeding, the first choice of coconut shavings, broken bricks, water moss mixed substrate, summer should be in a semi-shade and half yang environment, autumn to December should see more sunlight, during the growth period to keep the soil dry, spring and autumn every 25 days or so to apply a nitrogen fertilizer solution, after the flowering of April 5 months and 9 October to apply one or two cake fertilizer.

Soil preparation is the basic element of the cultivation method and precautions of Cymbidium grandiflora, Cymbidium grandiflora belongs to epiphytic plants, the requirements for soil selection are also more special, the general selection of larger particles of culture substrate, coconut shavings, broken bricks, moss and other cultivation substances can be selected, the appropriate amount of base fertilizer can also be added before cultivation, and the appropriate amount of water can be poured after cultivation, not more watering.

Compared with the traditional orchid plants, the large-flowered orchid has slightly higher requirements for light, and the lack of light will lead to its weaker resistance, which will affect the growth and development of the large-flowered orchid, and the shading degree in spring is best between 20% and 30%, and the summer should be in a semi-shaded and half-yang environment, and the sun should be seen more from autumn to December, which is conducive to the growth and development of the large-flowered orchid.

The soil of the large-flowered orchid is better to be dry, so it does not need to be watered too much, it is generally watered once every 3 5 days in winter, and the number of watering starts to increase gradually in spring, and it can be watered once a day in summer, and each watering needs to be appropriate, and after summer, gradually reduce the number of waterings.

Because the cultivation of Cymbidium grandiflora is mostly used in the humus-rich soil, so the fertilization of Cymbidium grandiflora in the later stage is particularly important, 3 September should be selected more nitrogen fertilizer, October should be selected more phosphorus, potassium fertilizer should be used, in addition to 4 May and 9 October after flowering need to apply one or two cake fertilizer.

1. Pruning

Large-flowered orchid is usually propagated by dividing method, the leaves are long and green, the flowers are generally very delicate, do not need special pruning and care, occasionally weeds or miscellaneous leaves, dead leaves can be pruned, so that the large-flowered orchid flowers are more beautiful, and the end of the leaves of the large-flowered orchid can also be cut off, because the end is easy to yellow and wither.

2. Pest prevention

The insect pests of Cymbidium grandiflora generally have slugs, leaf mites and other pests, the pests of Cymbidium grandiflora generally occur on the back of the flowers and leaves, once the insect pests are more serious, the branches and leaves will turn yellow and gradually erode, at this time, it is necessary to spray slug nemesis or trichlorocidal insecticidal mites from the back of the flowers and leaves for control.

It is a plant that has been artificially improved, because there are many large flowers in orchids, so it is named Big-flowered orchid.

First, the breeding method.

1. Prepare soil.

Soil is the basic element of the cultivation of Cymbidium grandiflora, Cymbidium sylvestris belongs to epiphytic plants, the selection of soil requirements is also more special, generally need to choose a larger particle cultivation substrate, you can choose coconut shavings, broken bricks, moss, etc., add an appropriate amount of base fertilizer before cultivation, and then pour in the appropriate amount of water.

2. Sufficient light.

Compared with traditional orchids, Cymbidium grandiflora has relatively high light requirements, and insufficient light will cause its resistance to weaken, which will affect the growth and growth of Cymbidium grandiflora.

It needs proper shading in spring, and it should be cultivated in a semi-shaded and half-sunny environment in summer, and it should be more visible in autumn and winter, which is conducive to its growth and development.

3. Reasonable watering.

The soil of the orchid is better to be dry, not to water too much water, generally 3-5 days in winter watering once as well, the spring weather weather temperature rises, the number of watering should gradually increase, to the summer can be watered once a day, each watering should be appropriate, so as not to cause soil waterlogging, after the summer to reduce the number of watering.

4. Regular fertilization.

Most of the humus-rich soil is used in cultivation, so it is particularly important to pay special attention to the fertilization of C. grandiflora in the later stage, and the fertilizer with more nitrogen content should be selected from March to September, and the fertilizer with more phosphorus and potassium fertilizer should be selected after October.

2. Precautions.

Cymbidium grandiflora generally adopts the method of dividing and propagating, so there is no need for special pruning, and occasionally weeds or weeds can be pruned to make it more beautiful, and the end of its leaves can also be pruned off, because the end is very easy to turn yellow and wither.

The insect pests of Cymbidium grandiflora are generally slugs, leaf mites, etc., and the leaves will turn yellow and gradually erode when they are serious, and they can be sprayed from behind the flowers and leaves with slug busters or trichlorocidal insecticidal mites for control.

Cultivation methods and precautions of Cymbidium grandiflora

First, the breeding method.

1. Moisture: It has no special requirements for moisture, just pour sufficient water during the growing season. Water more when the temperature is hot, reduce the amount of water when the temperature is cold, and also pay attention to the water temperature not too low to avoid frostbite on the plant.

3. Sunlight: It is suitable for growing in 50% shade, and let the plant be exposed to more sunlight in early autumn, so that its flowers will be better looking and healthy.

4. Fertilizer: It has strict requirements for fertilizer, and nitrogen, phosphorus, and potassium fertilizer should be applied in accordance with the ratio of 1:1:1.

2. Precautions.

1. When the breeding time is long, the flower soil should be changed, generally once every 1-2 years.

2. If it is kept at home, it should be placed in a ventilated place.
